Thanks - that's really helpful.

In PBP, if I put:

forward CON "+"

Then presumably this has defined a byte whose binary value is equal to the ASCII code for the character "+"?

If I then say

hserin[direction]

IF direction = forward THEN


Then to get this to succeed I would have had to ensure that the byte received and stored in the variable 'direction' had a value equal to the ascii code for the "+" character...?


Thanks - Ben
